The image in Figure 1 visually describes the area in a Word document from which to find the Check Accessibility feature. Add an alternative description – called alt text -- so the image conveys the same information audibly as it does visually.
Alt text for this image might be “Find the Check Accessibility tool from the File tab in the Check for Issues section”.
